Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB2011SA2G31 is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Current and voltage ratings (0.4VA at 28V AC/DC)
• Mounting type (Through Hole, Right Angle)
• Termination style (PC Pin)
• Switch function (On-Mom momentary operation)
• Operating temperature range (-30°C to 85°C)
• Mechanical and electrical life specifications

The substitute part MBN15SA2G31 is identified as a manufacturer-recommended equivalent. Substitution eligibility is based on functional and electrical parameter alignment within the constraints of the MB2000 series family and NKK Switches product portfolio.
